Introduction

Geosoft executables (GX’s) are custom software modules for use with the Geosoft Oasis montaj™ geophysical data processing system, which currently runs under the Microsoft Windows™ 2000 or XP operating systems. The U.S. Geological Survey (USGS) uses Oasis montaj™ primarily for the processing and display of airborne geophysical data. The ability to add custom software modules to the Oasis montaj™ system is a feature employed by the USGS in order to take advantage of the large number of geophysical algorithms developed by the USGS during the past half century.

This main part of this report, along with Appendix 1, describes Version 2.0 GX’s developed by the USGS or specifically for the USGS by contractors. These GX’s perform both basic and advanced operations. Version 1.0 GX’s developed by the USGS were described by Phillips and others (2003), and are included in Version 2.0. Appendix 1 contains the help files for the individual GX’s.

Appendix 2 describes the new method that was used to create the compiled GX files, starting from legacy Fortran source code. Although the new method shares many steps with the approach presented in the Geosoft GX Developer manual, it differs from that approach in that it uses free, open-source Fortran and C compilers and avoids all Fortran-to-C conversion.
